Which OECD guidelines are commonly used for reproductive toxicity testing?

411 Developmental Toxicity; 520/521 Reproductive Toxicity; 600 Extended One-Generation.

414 Developmental Toxicity; 421 Reproductive Toxicity; 443 Extended One-Generation Reproductive Toxicity.

412 Developmental Toxicity; 421/423 Reproductive Toxicity; 443 Extended One-Generation.

The OECD guidelines commonly used for reproductive toxicity testing include 414, 421/423, and 443.

A standard toolkit used in regulatory toxicology for reproductive toxicity combines developmental and reproductive endpoints across generations. Developmental Toxicity is assessed with a guideline that looks for effects on fetal development and malformations when the mother is exposed. Reproductive Toxicity Screening tests provide an initial, efficient look at potential adverse effects on reproduction and development. The Extended One-Generation Reproductive Toxicity Study builds on this by evaluating reproductive and developmental outcomes across a generation, capturing potential effects that emerge over time. Together, these guidelines cover both prenatal development and multi-generation reproductive effects, which is why this combination is commonly cited. The other options mix in guidelines that aren’t aligned with reproductive toxicity testing or omit the multi-generation aspect, making them less representative.
